$GNZDA,hhmmss.00,dd,mm,yyyy,+00,00*[checksum]
The ZDA output message header includes the talker ID for the currently enabled GNSS system or
systems as described in Section
3.3.4 .
3.3.14 GPS:PASHR <int> [0,255]
The NMEA string $PASHR,POS has been added for compatibility to legacy GPS hardware. The
PASHR command alongside the GPZDA command will give all relevant parameters such as time,
date, position, velocity, direction, altitude, quality of fix, and more. As an example, the String has the
following data format:
$PASHR,POS,0,12,191512.00,3610.11157,N,11518.89941,W,00887.70,????,000.00,000.01,-00.00,
00.0,00.8,00.0,00.0,0.46*21
Please note that the length of the string is fixed at 115 characters plus the two binary 0x0d, 0x0a
termination characters.
$PASHR,POS,0,aa,bbbbbb.00,cccc.ccccc,d,eeeee.eeeee,f,ggggg.gg,hhhh,iii.ii,jjj.jj,kkkk.kk,ll.l,
mm.m,nn.n,00.0,p.pp*[checksum]
Where:
aa: Number of Sats
bbbbbb.00: Time of Day UTC
cccc.ccccc,d: Latitude,S/N
eeee.eeeee,f: Longitude,W/E
ggggg.gg: Antenna Height in meters
hhhh: Four fixed ‘?’ symbols
iii.ii: Course Over Ground
jjj.jj: Speed in Knots
kkkk.k: Vertical Velocity in meters/s
ll.l: PDOP
mm.m HDOP
nn.n VDOP
00.0: Static number
p.pp: Firmware Version
This command instructs the Micro-JLT GNSS™ to send the NMEA standard string $PASHR every
N seconds, with N in the interval [0,255]. The command is disabled until the GNSS receiver achieves
a first fix.
This command has the following format:
GPS:PASHR <int> [0,255]
